Creating Mechanical Movements: Rules and
Behaviors

The basic movement of a metronome is to go back and forth, thus having a
cyclic movement. The speed of the cycle depends on the position of the weight.
You will implement this logic using rules and behaviors.

Metronome Rules and Behaviors

Create a Group and name it ''Position the metronome.'' Drag and drop a Change
Attribute behavior and change metronome.Position.X to 160. Drag and drop a
second Change Attribute behavior and change metronome.Position.Y to 240.
